[0002] In secondary structure construction, structural columns are often used as stable structures. Structural column construction is an important part of building construction, and its quality and stability are directly related to the safety and durability of the entire building. When the horizontal length of the infill wall exceeds 5m or there is no concrete column at the end of the wall, structural columns should be set in the middle and end of the wall.

[0022] Preferably, the ground needs to be cleaned before the wall is laid out and positioned, and the wall edge line and the structural column positioning line are popped out according to the main body axis and the control line;

[0023] When laying the blocks, tooth joints must be left, with the blocks first retreating and then advancing, with the advance and retreat dimensions greater than or equal to 60 mm and the height less than or equal to 300 mm. Horizontal tie bars are set every 500 mm along the wall height.

[0024] Preferably, a release agent is applied to the external corner aluminum formwork and the internal corner aluminum formwork before installation, and adhesive strips are affixed to both sides of the tooth joint. Then, the external corner aluminum formwork and the internal corner aluminum formwork are installed. The thickness of the external corner aluminum formwork and the internal corner aluminum formwork is 4 mm. Then, tension bolts are used to reinforce the formwork through the first reinforcement angle plate and the second reinforcement angle plate. Finally, a plurality of diagonal braces are used to support the bottom of the first reinforcement angle plate and the second reinforcement angle plate on the external corner aluminum formwork and the internal corner aluminum formwork, respectively.

[0025] Preferably, before pouring the concrete, 50mm cement mortar is laid on the structural columns and construction joints. During pouring, the concrete is poured into the structural columns at the discharge funnel. The concrete is poured in layers, with each layer not exceeding 600mm.

The construction method of the L-shaped rotatable assembled fixed structural column template is that during the installation of the structural column template of the L-shaped secondary structure, the positive angle aluminum template and the negative angle aluminum template are fitted with the positive angle and negative angle of the L-shaped secondary block structure by tension bolts, and auxiliary support is provided by diagonal braces. After the structural column is cast, the positive angle aluminum template and the negative angle aluminum template can be disassembled, so that the L-shaped rotatable assembled fixed structural column template can be used for multiple turnovers, avoiding material waste during conventional wooden template construction, ensuring the overall performance of the template installation, and improving the visual effect of the finished product. It can not only speed up the construction progress and reduce costs, but also ensure the quality of the project.

[0030] 2. The construction method of the L-shaped revolving assembled fixed structural column formwork is as follows: during use, a release agent is applied before the installation of the external angle aluminum formwork and the internal angle aluminum formwork, and adhesive strips are attached on both sides of the block tooth joint, and then the external angle aluminum formwork and the internal angle aluminum formwork are installed. The role of the release agent is to reduce the adhesion between the formwork and the concrete, so that the formwork can be easily removed from the concrete structure after the concrete hardens. The role of the adhesive strip is to prevent the concrete from leaking out from the gap between the formworks during the pouring process, and it can also protect the integrity of the block tooth joint to avoid damage during the pouring process.

[0031] 3. The construction method of the L-shaped revolvable assembled fixed structural column formwork uses tension bolts to reinforce the formwork through the first reinforcement angle plate and the second reinforcement angle plate. The function of the tension bolts is to provide additional tension to ensure that the formwork does not move or deform during the pouring process. The first reinforcement angle plate and the second reinforcement angle plate are used to disperse the tension of the tension bolts and protect the corners of the formwork from damage. Multiple diagonal braces are used to support the bottom of the first reinforcement angle plate and the second reinforcement angle plate on the external angle aluminum formwork and the internal angle aluminum formwork respectively. The function of the diagonal brace is to provide additional support to ensure that the formwork can remain stable during the pouring process. By adjusting the angle and position of the diagonal brace, the verticality and horizontality of the formwork can be further ensured. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] The embodiment of the present application provides a construction method for an L-shaped, rotatable, assembled, and shaped structural column formwork, thereby solving the problem that wooden formwork is generally used for corner structural column formworks. The reinforcement work is usually carried out using wooden squares, tension bolts, and woodworking clamps, which results in complicated construction procedures, waste of materials, and poor finished product effects, which not only increases construction costs, but also affects the overall construction quality.

[0039] During the installation of the structural column template of the L-shaped secondary structure, the outer angle aluminum template 1 and the inner angle aluminum template 2 are fitted with the outer angle and the inner angle of the L-shaped secondary block structure by means of tension bolts 7, and auxiliary support is provided by diagonal braces 8. After the structural column is cast, the outer angle aluminum template 1 and the inner angle aluminum template 2 can be disassembled, so that the L-shaped rotatable assembled fixed structural column template can be rotated for multiple times, avoiding material waste during conventional wooden template construction, ensuring the overall performance of the template installation, and improving the visual effect of the finished product. It can not only speed up the construction progress and reduce costs, but also ensure the quality of the project.

[0040] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0041] The embodiment of the present invention discloses a construction method of an L-shaped rotatable assembled fixed structural column formwork.

[0042] According to the attached Figure 1-3 As shown, the following steps are included:

[0043] Step 1: Wall layout and positioning;

[0044] Step 2: Planting and tying reinforcement bars in structural columns;

[0045] Step 3: Block laying;

[0046] Step 4: Installation of aluminum formwork for structural columns;

[0047] Step 5: Concrete pouring;

[0048] Step 6: Remove the aluminum formwork of the structural column;

[0049] Step 7: Curing of finished concrete;

[0050] The L-shaped revolvable assembled fixed structural column formwork adopted in the above construction method specifically includes:

[0051] A positive angle aluminum template 1, which fits the positive angle of the block, and a first reinforcing angle plate 5 is arranged on the outer side of the positive angle aluminum template 1;

[0052] Internal angle aluminum formwork 2, which fits the internal angle of the block, and a second reinforcing angle plate 6 is provided on the inner side of the internal angle aluminum formwork 2;

[0053] The tension bolts 7 are installed on the first reinforcement angle plate 5 and the second reinforcement angle plate 6, and are arranged through the external angle aluminum formwork 1 and the internal angle aluminum formwork 2;

[0054] There are multiple diagonal braces 8, and the multiple diagonal braces 8 support and position the positions of the external angle aluminum formwork 1 and the internal angle aluminum formwork 2.

[0055] During the installation of the structural column template of the L-shaped secondary structure, the outer angle aluminum template 1 and the inner angle aluminum template 2 are fitted with the outer angle and the inner angle of the L-shaped secondary block structure by means of tension bolts 7, and auxiliary support is provided by diagonal braces 8. After the structural column is cast, the outer angle aluminum template 1 and the inner angle aluminum template 2 can be disassembled, so that the L-shaped rotatable assembled fixed structural column template can be rotated for multiple times, avoiding material waste during conventional wooden template construction, ensuring the overall performance of the template installation, and improving the visual effect of the finished product. It can not only speed up the construction progress and reduce costs, but also ensure the quality of the project.

[0056] Furthermore, a first reinforcing transverse plate 3 and a second reinforcing transverse plate 4 are fixedly mounted on the outer side of the external angle aluminum formwork 1 and the inner side of the internal angle aluminum formwork 2, respectively.

[0057] Furthermore, the first reinforcing angle plate 5 and the second reinforcing angle plate 6 are respectively embedded in the first reinforcing transverse plate 3 and the second reinforcing transverse plate 4 .

[0058] Furthermore, a feeding funnel 9 is provided on the top of the external angle aluminum template 1.

[0059] Furthermore, the ground needs to be cleaned before the wall is laid out and positioned, and the wall edge line and structural column positioning line are popped out according to the main axis and control line;

[0060] When laying blocks, tooth joints must be left, first retreating and then advancing, with the advance and retreat dimensions greater than or equal to 60mm and the height less than or equal to 300mm. Horizontal tie bars are set every 500mm along the wall.

[0061] Leaving tooth joints when laying blocks and setting horizontal tie bars are important measures to ensure the integrity and stability of the wall structure. Tooth joints are a method of laying brick walls with joints. When the masonry cannot be laid at the same time, tooth joints are generally reserved at the junction to maintain the integrity and stability of the masonry. It is often used in the connection between structural columns and walls. It is the protruding part of the structural column. Horizontal tie bars are used to enhance the integrity and stability of the wall. Especially in high-height walls, setting horizontal tie bars can effectively prevent the wall from cracking or collapsing due to lateral forces.

[0062] It is particularly disclosed that before the external angle aluminum template 1 and the internal angle aluminum template 2 are installed, a mold release agent is applied, adhesive strips are pasted on both sides of the tooth joint, and then the external angle aluminum template 1 and the internal angle aluminum template 2 are installed.

[0063] During use, a release agent is applied before installing the external angle aluminum formwork 1 and the internal angle aluminum formwork 2, and adhesive strips are attached to both sides of the block tooth joints. Then the external angle aluminum formwork 1 and the internal angle aluminum formwork 2 are installed. The role of the release agent is to reduce the adhesion between the formwork and the concrete, so that the formwork can be easily removed from the concrete structure after the concrete hardens. The role of the adhesive strips is to prevent the concrete from leaking out from the gaps between the formworks during the pouring process, and at the same time, it can also protect the integrity of the block tooth joints and avoid damage during the pouring process.

[0064] The thickness of the external angle aluminum formwork 1 and the internal angle aluminum formwork 2 is 4 mm. Then, tension bolts 7 are used to reinforce the first reinforcing angle plate 5 and the second reinforcing angle plate 6. Finally, multiple diagonal braces 8 are used to support the bottom of the first reinforcing angle plate 5 and the second reinforcing angle plate 6 on the external angle aluminum formwork 1 and the internal angle aluminum formwork 2 respectively.

[0065] It is particularly disclosed that before pouring concrete, 50mm cement mortar is laid on the structural columns and construction joints. During pouring, concrete is poured into the structural columns at the discharge funnel 9. The pouring process is carried out in layers, with each layer not exceeding 600mm. Vibrate while pouring, and pull out while vibrating to avoid direct contact with steel bars and brick walls. Check whether the steel bars are displaced and whether the tension bolts 7 are loose.

[0066] A 50mm thick cement mortar is laid at the structural columns and construction joints. This step is to improve the bonding force between the concrete and the foundation or old concrete, thereby enhancing the integrity of the structure. The concrete is poured into the structural columns using the discharge funnel 9. This step should ensure the uniformity and continuity of the concrete.

[0067] During the pouring process, the falling height of the concrete should be controlled to avoid excessive impact force that may cause the steel bars to shift or the formwork to deform. When pouring concrete, it should be poured in layers, with the height of each layer not exceeding 600mm. This step is to ensure the density and uniformity of the concrete, and to facilitate vibration and exhaust.

[0068] Use tension bolts 7 to reinforce the formwork through the first reinforcement angle plate 5 and the second reinforcement angle plate 6. The function of the tension bolts 7 is to provide additional tension to ensure that the formwork will not be displaced or deformed during the pouring process. The first reinforcement angle plate 5 and the second reinforcement angle plate 6 are used to disperse the tension of the tension bolts to protect the corners of the formwork from damage. A plurality of diagonal braces 8 are respectively supported against the bottom of the first reinforcement angle plate 5 and the second reinforcement angle plate 6 on the external angle aluminum formwork 1 and the internal angle aluminum formwork 2. The function of the diagonal brace 8 is to provide additional support to ensure that the formwork can remain stable during the pouring process. By adjusting the angle and position of the diagonal brace 8, the verticality and horizontality of the formwork can be further ensured.

[0069] It is particularly disclosed that after the concrete strength of the structural column reaches the requirement, the outer corner aluminum formwork 1 and the inner corner aluminum formwork 2 are removed, and the trumpet formed by the concrete at the discharge funnel 9 is removed.

[0070] Furthermore, the finished concrete is cured by watering, and the curing time is greater than or equal to 7 days.

[0071] During the installation of the structural column template of the L-shaped secondary structure, the outer angle aluminum template 1 and the inner angle aluminum template 2 are fitted with the outer angle and the inner angle of the L-shaped secondary block structure by means of tension bolts 7, and auxiliary support is provided by diagonal braces 8. After the structural column is cast, the outer angle aluminum template 1 and the inner angle aluminum template 2 can be disassembled, so that the L-shaped rotatable assembled fixed structural column template can be rotated for multiple times, avoiding material waste during conventional wooden template construction, ensuring the overall performance of the template installation, and improving the visual effect of the finished product. It can not only speed up the construction progress and reduce costs, but also ensure the quality of the project.

[0072] Leaving tooth joints when laying blocks and setting horizontal tie bars are important measures to ensure the integrity and stability of the wall structure. Tooth joints are a method of laying brick walls with joints. When the masonry cannot be laid at the same time, tooth joints are generally reserved at the junction to maintain the integrity and stability of the masonry. It is often used in the connection between structural columns and walls. It is the protruding part of the structural column. Horizontal tie bars are used to enhance the integrity and stability of the wall. Especially in high-height walls, setting horizontal tie bars can effectively prevent the wall from cracking or collapsing due to lateral forces.

[0073] During use, a release agent is applied before installing the external angle aluminum formwork 1 and the internal angle aluminum formwork 2, and adhesive strips are attached to both sides of the block tooth joints. Then the external angle aluminum formwork 1 and the internal angle aluminum formwork 2 are installed. The role of the release agent is to reduce the adhesion between the formwork and the concrete, so that the formwork can be easily removed from the concrete structure after the concrete hardens. The role of the adhesive strips is to prevent the concrete from leaking out from the gaps between the formworks during the pouring process, and at the same time, it can also protect the integrity of the block tooth joints and avoid damage during the pouring process.

[0074] Use tension bolts 7 to reinforce the formwork through the first reinforcement angle plate 5 and the second reinforcement angle plate 6. The function of the tension bolts 7 is to provide additional tension to ensure that the formwork will not be displaced or deformed during the pouring process. The first reinforcement angle plate 5 and the second reinforcement angle plate 6 are used to disperse the tension of the tension bolts to protect the corners of the formwork from damage. A plurality of diagonal braces 8 are respectively supported against the bottom of the first reinforcement angle plate 5 and the second reinforcement angle plate 6 on the external angle aluminum formwork 1 and the internal angle aluminum formwork 2. The function of the diagonal brace 8 is to provide additional support to ensure that the formwork can remain stable during the pouring process. By adjusting the angle and position of the diagonal brace 8, the verticality and horizontality of the formwork can be further ensured.
